Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566326, here are decompositions:

37 + 31566289 = 31566326
79 + 31566247 = 31566326
157 + 31566169 = 31566326
283 + 31566043 = 31566326
307 + 31566019 = 31566326
313 + 31566013 = 31566326
373 + 31565953 = 31566326
397 + 31565929 = 31566326

Showing the first eight; more decompositions exist.
